Description

Steel structure column base Technical Field The utility model mainly relates to the technical field of steel structures, in particular to a steel structure column base. Background Steel structures are structures composed of steel materials, and are one of the main types of building structures. The structure mainly comprises beam steel, steel column, steel truss and other components made of section steel, steel plate and the like, and rust removal and prevention processes such as silanization, pure manganese phosphating, washing, drying, galvanization and the like are adopted. The components or parts are typically joined by welds, bolts or rivets. Because the self weight is lighter, and the construction is simple and convenient, the method is widely applied to the fields of large-scale factory buildings, venues, super high-rise buildings and the like. Some steel structure column bases are often fixed by bolts, but under the condition that the bolts bear repeated loads or dynamic loads, the bolts can loose, so that the stability of the whole structure is reduced, and the safety of the structure is affected. Disclosure of utility model The utility model mainly provides a steel structure column base for solving the technical problems in the background art. The technical scheme adopted for solving the technical problems is as follows: The steel structure column base comprises a column body and a connecting pier, wherein a connecting bottom plate is arranged at the bottom of the column body, and a plurality of threaded holes are formed in the connecting bottom plate; The positioning bolt is arranged in the threaded hole, a positioning hole matched with the positioning bolt is formed in the connecting pier, a cavity is formed in one side of the positioning bolt, a clamping assembly is arranged on the positioning bolt and comprises a positioning shaft penetrating through the cavity, a pull button arranged at the top of the positioning shaft, a disc positioned on the positioning shaft inside the cavity and a spring sleeved on the positioning shaft at the top of the disc, and a clamping groove matched with the positioning shaft is formed in the connecting bottom plate. Optionally, the connecting pier is provided with a mounting groove matched with the connecting bottom plate. Optionally, a plurality of wedge blocks are equidistantly arranged on the connecting bottom plate and connected with the side wall of the column body. Optionally, the positioning bolt is a cross bolt. Optionally, the side surface of the pull button is provided with anti-slip stripes. Optionally, a plurality of the threaded holes are respectively positioned at four corners of the connecting bottom plate. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the column body is connected with the connecting pier, and after the positioning bolt is stably installed, the positioning bolt can be stably inserted into the clamping groove of the connecting bottom plate through the positioning shaft of the clamping assembly, so that the positioning bolt is prevented from loosening, and the safety of the steel structure is ensured. The utility model will be explained in detail below with reference to the drawings and specific embodiments.
